50 is in the tents place while 5000 is in the hundred place
the first five only has one zero so it is in the tens place. and the other five is in the thousand place because it has three zeros
First Part:
A cube has all equal sides and therefore the formula of:
-Volume of Cube=side³
=3³=27 cm³
-Volume of Cuboid=Area of base×Height of prism
1st prism =4×3×1=12 cm³
2nd prism =7×4×9=252 cm³
3rd prism =3.5×5×6=105 cm³
Second part:
Volumes are given with one side missing
V=Area of base×Height of Prism
1st prism
360=6×12×x
360=72x

=

5 cm=x
Check: V=6×12×5=360 cm³
2nd question:
break it into 2 parts:
1st: find the volume of the first cuboid:
V=3×3×4=36 cm³
So now we know the volume of the second cuboid since both of them have the same volume.
2nd: 36=6×4×x
36=24x

1.5 cm=x
Check: 1.5×6×4=36 cm³
Answer:
diameter
circumference

diameter
Step-by-step explanation:
First, find the length of the diameter (d) and the length of the circumference of the circle (c).
Next, divide the length of the circumference c by the length of the diameter d and set up an equation

where the ratio equals to
(the definition of
)
Then, solve the equation for the circumference c:

Finally, substitute 2 times the radius for the diameter

Answer:
the first one
Step-by-step explanation:
the 4x's cancel out and 8 does not equal -14 so...
For this case we must resolve the following inequality:

Subtracting 7 from both sides of the inequality we have:

Dividing by 3 to both sides of the inequality we have:

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

Thus, it is observed that to solve the inequality it is necessary to change the meaning of it.
ANswer:
False. It is necessary to change the sense of inequality
